I have successfully mated the VRC with VR-Ms (VR-M60s front L/R and VR-M50s rear L/R). Been going strong for nearly 15 years and I have zero desire to make changes in the speaker department (though, someday in the semi-distant future, I suppose I'll have to consider it if I ever go for something more than 5.1).The VRC is from the same line and shouldn't be underestimated. It's excellent with dialogue but a bit lacking in the bass department which should be expected, given the smaller mid-bass drivers. I have had a few of the the VR tweeter line and still find the VR920 to be the best of them. Given that you have towers, try crossing the VRC a lil higher than 80.
I have my VRC crossed at 80 HZ and it sounds fine--I do have a somewhat "near field" array (nothing more than 7 feet from the main listening position, 6 for the VRC) so I don't often push my speakers to the point where any of them might run out of steam.
Just my 2 cents.
